It often involves various tests and examinations, such as blood tests, imaging studies, and physical assessments, to gather information about the patient's health. The goal of diagnostics is to provide accurate information that helps healthcare professionals, like doctors and nurses, make informed decisions about treatment options. Effective diagnostics can lead to early detection of illnesses, improving the chances of successful treatment and better patient outcomes.
